β2 adrenergic receptor

Dopexamine is a dopamine analogue with agonist activity at β2 and dopaminergic receptors. Dopexamine can attenuate the systemic inflammatory response, reduce tissue leukocyte infiltration, and protect against organ injury at doses that do not alter global hemodynamics or regional microvascular flow. Dopexamine is a dopamine analog that stimulates β-adrenergic and dopamine 1 and 2 receptors, conferring some vasodilatory effects. Dopexamine reduces the systemic inflammatory response to endotoxin, including cytokine release, endothelial adhesion molecules, and oxidative stress, without substantially changing systemic hemodynamics, either blood pressure or stroke volume.
